      PL SQL Function :

      CREATE FUNCTION SplitString
      (
      -- Add the parameters for the function here
      @myString varchar(500),
      @deliminator varchar(10)
      )
      RETURNS
      @ReturnTable TABLE
      (
      -- Add the column definitions for the TABLE variable here
      [id] [int] IDENTITY(1,1) NOT NULL,
      [part] [varchar](50) NULL
      )
      AS
      BEGIN
      Declare @iSpaces int
      Declare @part varchar(50)

          --initialize spaces
          Select @iSpaces = charindex(@deliminator,@myString,0)
          While @iSpaces > 0
      
          Begin
              Select @part = substring(@myString,0,charindex(@deliminator,@myString,0))
      
              Insert Into @ReturnTable(part)
              Select @part
      
      Select @myString = substring(@mystring,charindex(@deliminator,@myString,0)+ len(@deliminator),len(@myString) - charindex(' ',@myString,0))
      
      
              Select @iSpaces = charindex(@deliminator,@myString,0)
          end
      
          If len(@myString) > 0
              Insert Into @ReturnTable
              Select @myString
      
      RETURN 
      

      END
      GO

      And Try with Example

      Select * From SplitString('Hello John Smith',' ')

            this one worked. DECLARE @mystring VARCHAR(200) DECLARE @count INT DECLARE @max INT DECLARE @space INT SET @mystring = 'A quick sly fox jumped over the lazy brown dog' SET @count = 0 SET @max = 7 SET @space = 1 SET NOCOUNT ON WHILE @count < @max BEGIN SELECT @space = CHARINDEX (' ', @mystring , @space + 1) -- SELECT 'position: ', @space SET @count = @count + 1 END SELECT LEFT(@mystring,@space) SET NOCOUNT OFF

                I have like 1000 rows returning from database is string.split and looping to get the 7 words appropriate way to go?

                Then why you are not doing this thing in DB End ? Make the stored procedure which will return those first 7 words from DB rather than whole sentence.

                      Ok, I think via database it works but I need to use this logic via c# code. could someone please show me how to write a function that will give me same output. thanks in advance below code runs two times and prints it twice. how can i make it more efficient so it loads faster and dispalys only once?

                      public string getAdBrief(string text)
                      {
                      string s = "";
                      string[] words = text.Split(' ');
                      for (int i = 0; i < 7; i++)
                      {
                      s +=words[i] + ' ';
                      }
                      return s;
                      }
